17 Claims.

This invention relates to improvements in sink mountings for installing a standard flat flange type sink in an opening in a drainboard or the like.

It is an object of the invention to provide improved mounting means particularly adapted for rigidly securing a sink of the flat flange type in an opening in a linoleum covered plywood drainboard or the like and providing a watertight seal between the sink and the drainboard.

It is a more specific object of the invention to provide a sink mounting fixture for the purpose described which comprises a sealing memher having a top portion which covers the space between the edge of the sink and the drainboard and having a downwardly extending web portion which is positioned between the edge of the sink and the drainboard and which is provided with spaced clamping means for clamping engagement with the sink rim on one side thereof and for clamping engagement with the drainboard on the other side thereof.

It is a further object of the invention to provide a simple mounting fixture for a flat flange type sink which is so constructed that it may be first secured in position on the sink rim and then secured to the drainboard after positioning in the opening provided therein.

These and other objects will be apparent from a description of the preferred form of the invention which is shown by way of illustration in the accompanying drawings, wherein:

Fig. 1 is a top plan of the sink installed in a drainboard with a mounting means embodying the principles of the invention;

Fig. 2 is a section on the line 2-2 of Fig. l, to an enlarged scale;

Fig. 3 is a perspective view of a portion of the mounting fixture; and

Fig. 4 is a, plan view of a sink with the mounting fixture partially positioned thereon.

In the preferred form of the invention which is illustrated in the drawings, there is provided a mounting and sealing ring member ID for securing a sink II in position in an aperture I2 which is provided in the drainboard l3. The sink II is a standard type having an outwardly directed top rim or flange I4 and the drainboard is a conventional plywood structure having a linoleum top I5. The drainboard I3 may be of any depth since the fixture is particularly designed to be used in drainboards of varying thicknesses. The aperture I2 is larger than the periphery of the sink II to provide space for the ring member I0.

The sink mounting fixture I0 is preferably constructed of an extruded section of metal such as aluminum or similar material having sufficient resiliency to permit bending in order to install the same on the flange I4 of the sink. The member I0 is formed into a split ring to surround the four sides of the sink. In cross section the member ID, as illustrated in Fig. 2 comprises a vertically positioned web portion I6 terminating at the top in an inwardly extending flange I! which is positioned over the edge of the sink rim I4 and an outwardly extending flange I8 which is positioned over the linoleum top I5 of the drainboard I3. The edges of the flanges I1 and I8 may be rounded or feathered as desired to insure a relatively smooth surface between the sink II and the drainboard I3. The vertical web portion I6 of the mounting member I0 terminates at the bottom in an inwardly directed flange I9. The bottom flange I9 cooperates with the top flange I! to form a channel or recess for receiving the edge of the sink rim I4. A plurality of bolts 20 are arranged in threaded engagement in apertures 2| extending in spaced relation around the peripheral edge of the sink. The bolts 20 are of suflicient length to clamp between the flange I1 and I9 sink rims of varying thicknesses.

The web portion I6 of the fixture I0 is provided with a plurality of upwardly and outwardly extending bolts 22 which are received in threaded engagement in spaced apertures 23. The bolts 22 are of such a length that their ends project outwardly and. upwardly of the outer surface of the web I 6 and engage or bite into the adjacent wall 24 of the drainboard I3 as at the point 25 in Fig.

2. The bolts 22 are placed at such an angle and are of sufficient length to insure substantial engagement of the ends with the wall surface 24 to rigidly clamp the fixture to the drainboard I3 with the flange I8 in clamping engagement with the linoleum top I5. The clamping bolts 22 and 20 are preferably arranged in alternate spaced relation around the periphery of the sink.

In installing a sink with the fixture I0 the fixture be first placed at the desired location on the drainboard I3 and the base of the web portion I5 may be used to mark out the necessary aperture 12 to be cut in the drainboard. After the aperture 52 has been cut the fixture I0 is sprung apart suificiently (Fig. 4) to position it on the sink II with the sink rim I4 extending into the channel or recess provided between the portions IT and is of the fixture. The clamping bolts 20 are then inserted and taken up to clamp of the fixture meet may be closed by merely loos-- f ening the clamping bolts 2t and drawing up bolts 22 after which bolts 25 may again be drawn up into clamping engagement. 7

While specific details of construction and materials have been referred to in describing the preferred form of the invention, it will be understood that other details of construction and other materials may be resorted towithin the spirit of the invention.
